The Bump backpack by Master-Piece is a roomy, water-resistant carry-all that incorporates cutting-edge weight and temperature-distributing technology. Ideal for daily use, whether for short excursions or extended travels, the Bump features an expandable main compartment secured with a lockable Dulles quick-release clasp. The rear mesh panels can be detached and adjusted for a customised fit and optimal comfort. The straps and rear panel—areas that come into contact with the body—are crafted from Outlast® temperature-regulating material, originally developed for NASA, to help keep you warm or cool as needed. Additionally, the Bump is equipped with Master-Piece's innovative ‘M-Strap’ technology, which evenly distributes shoulder weight, alleviating strain during heavier loads and longer journeys.
